Abstract Traditional social network theory believes that social network ties innovators holding are helpful for improving innovators' performance. However, when considering the social network cost, the social network ties in different quality level may make different effects on innovators' performance. The objective data from LEGO Ideas open innovation platform was scrawled by crawler program to build the social network of platform users. And the heterogeneous effects of high-quality and lowquality social network ties on user innovation performance was tested. As a result, it was found that the quantity of social network ties platform users holding did not affect user innovation performance, while the quality of social network ties was the key point. Highquality ties can significantly increase the value of users' innovative output and significantly reduce the risk of elimination of users' creative ideas; while lowquality ties significantly reduced the value of users' innovative output and slightly increase the risk of elimination of users' creative ideas. Hence, we proposed the strategic suggestion for open innovation platforms and platform users.
